Answer :
A. Normalization. Normalization is a process used to organize a database in a way that reduces redundancy and dependency.
Normalization is a common technique used to improve the performance of a database by reducing the amount of data that needs to be accessed and processed. By organizing the data in a more efficient manner, normalization can help to improve the overall performance of a database, particularly when it is accessed frequently or by multiple users.
Client-side input validation and server-side input validation are both techniques used to validate user input and ensure that it is in the correct format. While these techniques can help to improve the security and reliability of a database, they are not directly related to performance and are not likely to have a significant impact on overall performance.
